This record describes Pachyneuron groenlandicum (species). Recorded family: Pteromalidae. Recorded order: Hymenoptera.
Identification and Appearance
| Feature | Description |
|---|---|
| Additional details | Length 1.5-2.6mm. |
| Head | Head and thorax varying from dull olive-green or bluish olive to a fairly bright green or blue-green. Femora often more or less infuscate, sometimes wholly pale, tibiae pale or with a fuscous subbasal ring. |
| Forewing | Forewing with marginal vein longer than stigmal vein, basal vein with 2-12 hairs, speculum open below, upper surface of costal cell often bare. |
| Thorax | Thorax arched dorsally, scutellum in profile appearing convex. Propedial nucha mainly to entirely reticulate. Gaster of female at least slightly less than twice as long as broad, average about 1-5 times. Unless identified by a recognised expert, a photo is required and the specimen should be examined with a microscope.

About Flies: the wider group
Order-level background for Hymenoptera, the group containing Pachyneuron groenlandicum. Species-specific details appear above.
Group overview
Hymenoptera includes over 150,000 described species of ants, bees, wasps, and sawflies. Earth harbors approximately 20 quadrillion (20×10^15) ants, with a combined biomass of ~12 megatons of dry carbon - exceeding the combined biomass of all wild birds and mammals (PNAS, 2022).
Ecological role of the group
About 35% of the world's food crops depend on animal pollinators. The chocolate industry, valued at over $100 billion, depends on pollinating flies and midges. Ants are the dominant soil engineers in most terrestrial ecosystems, turning more soil than earthworms in many habitats.
Economic and practical significance of the group
Pollinators contribute $235-577 billion worth of annual global food production (FAO). In the U.S., bee pollination alone benefits crops valued at $18 billion annually, and honey bees are responsible for $5.4 billion in agricultural productivity. Between April 2023-2024, 55.1% of managed honey bee colonies were lost. The U.S. bee population dropped from 5 million to 2.5 million.
